Definitions

  • the present invention relates to a motor-pump unit for a motor vehicle brake system, comprising a motor and a pump, which comprises a shaft driven by the motor, the shaft end of which is rotatably mounted in a receiving body provided with valves and connecting channels with at least one bearing, wherein the shaft drives displacement means that extend into a crankcase, and wherein the bearing is provided in front of a bearing plate of the engine between the crankcase and bearing plate.
  • Such a motor-pump unit is basically known.
  • the filling of a motor vehicle brake system with the required pressure medium after assembly of the individual system components such as in particular a master cylinder, a pipe and hose system, the motor-pump unit and wheel brakes at the vehicle manufacturer.
  • the entire brake system is evacuated in a first method step in order to supply the intended pressure medium in a second method step.
  • roller bearing assemblies of motor-pump units are exposed to high, as well as non-rolling stresses, especially during the Druckstoffbehellprozeß.
  • sealed bearings for example, to Ausknöpfen of sealing elements such as sealing lips.
  • the bearings fail prematurely, which is particularly problematic in brake systems with high pump running times, in particular electro-hydraulic brake systems.
  • Unsealed bearings have free access to the rolling surfaces, and do not allow the use of a special lubricant. This is problematic if the lubricating properties of the pressure medium used are insufficient or if the pressure medium contains wear products which can cause tread damage.
  • the invention is based on the object of providing an improved motor-pump assembly in which the risk of bearing damage and lubricant leaching from bearings is reduced.
  • a channel is provided, which connects a side facing away from the crank chamber of the bearing with a leakage drainage channel for the crankcase.
  • An advantageous embodiment of the embodiment has a channel which is provided in the receiving body.
  • the recordable leakage volume is further increased by opening the channel into a chamber bounded by the bearing shield and the receiving body, the chamber being connected to the leakage drainage channel.
  • a motor-pump unit 1 for use in a motor vehicle brake system is connected on the one hand to wheel brakes, not shown, and on the other hand to a donor, not shown, such as a master cylinder with a pressure medium reservoir.
  • a receiving body 2 has at least six hydraulic connections.
  • the unit is particularly suitable and intended for electro-hydraulic brake systems, which have a, on or in the receiving body 2 integrated high-pressure accumulator, which serves to feed the wheel brakes.
  • the master cylinder is here only in Emergency used for the brake application and serves primarily to simulate brake actuation forces.
  • the motor-pump unit 1 further includes a pump 3 for supplying the high-pressure accumulator or for supplying wheel brakes and a motor 4 for driving the pump 3.
  • An electronic unit 14 for controlling and regulating the system is located on a, the motor 4 opposite side the receiving body 2, wherein electronic control and supply lines of the motor 4 are passed through the receiving body 3.
  • the motor 4 drives a pump shaft 5 which is rotatably disposed within a stepped through-hole 6 by means of sealed bearings 7, 8.
  • Bearing 7 is designed as a fixed bearing, while bearing 8 is designed as a floating bearing, and therefore can not absorb axial forces.
  • the pump shaft 5 acts on displacement means for the pressure medium. In the illustrated, preferred embodiment, it is a radial piston pump which has as a displacement means via pump piston 9,10, which open into an approximately centered between the bearings 7,8 arranged space 11, and by an eccentric connected to the shaft (not graphically shown) are driven.
  • the number of pump pistons is in principle arbitrary, with 3 pistons being preferred because this reduces pulsations and noise.
  • a roller bearing 12 In order, for example, to provide pressure medium, which has accumulated in the chamber 11 as a result of internal leakage, to the system again (or if the space 11 is already flooded with pressure medium), a channel opens into the space 11 13, which communicates with the pressure fluid reservoir.
  • a motor facing away shaft end 15 extends into a space 16 and passes through a bottom 17 which is inserted into the through hole 6, and rests axially on an outer ring of the bearing 8. Between shaft 5 and a through hole through the bottom 17 is a gap for the passage of pressure medium.
  • connection 19 is designed as a channel 20, wherein its wall consists of peripheral regions of the inner ring and bearing seat.
  • the bearing seat 18 has a flattening 21, while the inner ring is unchanged annular, so that there is a crescent-shaped, free channel cross-section for pneumatic evacuation and the pressure medium passage between these adjacent components.
  • Eccentricity and channel 20 are arranged in alignment with each other for an unchanged good bearing seat in the axial direction, as is apparent from Fig. 2.
  • the flattening 21 is substantially in the same angular position as the Exzentermaximum (maximum stroke), as illustrated by a dashed line in Fig. 2. Because the maximum bearing forces are removed in the displacement stroke on the opposite side of the Exzentermaximum (from the perspective of the bearing inner ring), despite channel 20 no reduction of the effective, force-transmitting surface on the bearing seat. Bearing seat damage is excluded.
  • the flattening 21 can be replaced in principle by holes are provided which extend through the shaft interior.
  • the free space 16 is provided with a lid 22 formed as a closure, which prevents loss of pressure medium on the side of the electronic unit 14.
  • the cover is placed on a bore step 23 of the through hole 6 and caulked with the receiving body 2 liquid and gas-tight.
  • a sealing element 25 is provided between eccentric and bearing 7 in the region of the motor-side shaft end 24, which is arranged in a holding body 26, so that no leakage fluid can escape from the receiving body 2 in the direction of motor 4.
  • FIG. 3 is a flying bearing with a cantilevered shaft end removed.
  • Such flying bearing is widely used in engine-pump assemblies of vehicle brake systems.
  • the known constructions suffer from the disadvantage that alternating heating and cooling processes - in particular of the engine - can to a certain extent cause a suction, so that leakage fluid, which is located in the crank chamber, can pass as a result of a pressure difference in the engine compartment. Damage to the bearing lubricant filling or lubricant flushing as well as damage to the bearing sealant is possible.
  • the pump drive is a pump shaft 5 with an eccentric, which is arranged in the crank chamber 11.
  • a sealed bearing 7 which in front of a bearing plate 30 of the motor 4 between Crank 11 and end plate 30 is provided.
  • the bearing plate 30 is formed of plastic material, closes the pot-shaped motor housing and carries the sealed bearing 7 before the final assembly of motor 4 and receiving body 2 provisionally by a ring nozzle 31 surrounds a part of the bearing outer ring.
  • the crank chamber 11 is connected to a leakage drainage channel 32, which accumulate accumulated leakage fluid in a storage chamber 33 of the unit 1, stockpile, or for example can be discharged into the environment.
  • the receiving body 2 may have a tube 34 which extends into the storage chamber 33, wherein an outlet opening of the Tube 34 is arranged at a distance from the free liquid level.
  • the crankraumabgewandte side of the bearing 7 via one or a plurality of channels 13 connected to the leakage drainage channel 32.
  • the annular nozzle 31 has one or more channels 13, which extend in the direction of the crank chamber facing away from the bearing seat in the bearing plate 30, so that contact with the gap 35 can be produced, extending between a bulkhead of the bearing plate 30 and the side facing away from the crank of the bearing 7 is located.
  • Each channel 13 connects them Side facing away from the crankcase with the leakage drainage channel 32, which leakage fluid - which can accumulate in the crank chamber 11 and the gap 35 - either in the environment or in the storage chamber 33 derived. Due to the described features, the motor interior is protected in the region of the shaft outlet against the ingress of leakage fluid. Even if leakage fluid should pass through the bearing 7, this can be supplied to the already provided leakage circuit.
  • the system and in particular the bearing 7 is depressurized under pneumatic aspects by the connection to the ambient atmosphere. This prevents leakage fluid or ambient fluid from being forced under the action of a pressure gradient through the bearing 7 into the interior of the engine. It is also prevented that sealing discs of the bearing 7 can ausknumblen under the action of a pressure gradient.
  • the channel 13 may in principle be provided as a partial recess in the receiving body 2, as is apparent from Fig. 3. In principle, the channel 13 may also be provided on a bearing outer ring, but this requires a separate processing of this standardized component. In a not shown, modified embodiment, the channels 13 are provided in the receiving body 2.
  • the channel 13 does not have to open directly into the leakage drainage channel 32.
  • a chamber which is bounded by the end plate 30 and the receiving body 2.
  • the invention allows for extremely compact design a much improved protection of the motor. 4 against leakage fluid while avoiding residues of water and / or leakage fluid (brake fluid) within the unit.
  • the invention is applicable to a variety of pump types having so-called internal leakage.
  • the invention is in principle also suitable for use in conjunction with a gear pump, which has, for example, internal gear pairs as displacement means.
